Definitions
- FIG. 4 is a partially sectioned view taken along angled line 4--4 in FIG. 1 of the swivel base;
- FIG. 5 is a cross sectional view taken along line 5--5 of the diagonal in FIG. 1 with an isometric view of the swivel base and attached vertical post;
- the connector coupling assembly 28 of FIG. 1 further comprises a coupler 34 for clamping to the inner vertical post 32 at ring connector 36 (shown in phantom).
- the assembly 28 engages ring connector 36 by means of a downwardly extending finger 38 which interfits into one of the holes in ring connector 36.
- Swivel base 22 is optionally provided with a base pad 60 interposed between the base plate 61 of swivel base 22 and the sloping boiler wall 24.
- This base pad 60 provides a cushion for the base and avoids damage or scarring of the boiler wall.
- This base pad 60 may be formed of any suitable material including plywood or neoprene.
- Boiler 64 comprises a generally rectangular firebox whose lower walls 24 converge toward a throat 70. Ash and other byproducts of combustion fall through this throat 70 into an ash pit (not shown) for collection and removal. Although this throat opening to the ash pit may be up to 21/2 feet wide, this area often must be planked over to protect maintenance workers in the ash pit and is therefore not available as an access to the boiler. Alternatively, access to the interior of the boiler is gained through a manhole opening 72 provided in the sidewall of the boiler 64. This manhole 72 is typically quite small with diameters ranging from 18 to 30 inches. This limitation severely restricts the size and configuration of scaffolding components which can be passed through the manhole and assembled within the boiler.
- a support beam 74 is horizontally emplaced in the boiler throat 70 so as wedgingly to rest securely between opposite converging bottom walls 24. Screw leg 76 is then installed on a base saddle 78 to support vertical post 32a.
- the modularized horizontal members 80 are of set length, e.g. eight feet for members, 80d,80f, and seven feet for 80h,80l.
- Each post 32 usually includes four ring connectors and typically are six and one-half feet high.
